Tuning the conformational flexibility of quinoxaline cavitands for complexation at the gas-solid interface

The selectivity and efficiency of benzene and toluene uptake at the gas-solid interface by quinoxaline cavitands is strongly enhanced by partial rigidification of the receptor cavity and immobilization of the cavitand onto silica gel particles.

Automated summary

The selectivity and efficiency of benzene and toluene uptake at the gas-solid interface can be greatly improved by partially rigidifying the receptor cavity of quinoxaline cavitands and immobilizing them onto silica gel particles.
